Quasi-classical investigation of nonpolynomial central potentials with broken supersymmetry

We evaluate energy eigenvalues corresponding to different central potentials with nonpolynomial character and exhibiting broken supersymmetry. The calculations were carried out using numerical integration, the WKB rule, and a quasi-classical quantization rule for broken supersymmetry. It is shown that in most cases the quasi-classical rule gives far better estimates than the WKB rule applied separately to the supersymmetry partners.
